Grand Finale Galaxy
The Grand Finale Galaxy is the final galaxy in Super Mario Galaxy. The galaxy is unlocked after all 120 stars are obtained with Luigi. This galaxy has the 121st Power Star for both plumbers. The galaxy is Toad Town (also known as the Castle Gardens) from the beginning of the game. The only difference is that creatures from other parts of the game are there, including Penguins, Bees and Gearmos, the three major NPC types in the game. The Toad Brigade and their ship, the Starshroom, are found outside of the castle. After collecting all the Purple Coins, the Mailtoad will recieve a message. If you talk to him, he will send a congratulatory picture to the Wii message board. This pictures differs depending on whether you spoke to the Mailtoad with Mario or Luigi. The picture can also be sent to friends.
The Grand Finale Galaxy is reached by talking to the fourth Green Luma on the Trial Planet.
Interestingly, on the list of galaxies, it is simply called "Grand Finale", lacking the "Galaxy" name that all other galaxies use. This is likely because it is merely Toad Town and Princess Peach's Castle rather than a proper galaxy.
